Clytia (Clytia hemisphaerica)

Clytia hemisphaerica is a hydrazoan species. The medusa stages should be kept in a kreisel, pseudokreisel, or any tank with circular flow. The polyps can be kept in bare dishes or bowls without any special equipment. The polyps will settle on solid objects in their container such as glass/plastic slides or rocks. Once polyps have attached to a substrate and begin budding gonozooids in preparation for medusa release, the object bearing the colony should be transferred to a kreisel or medusa system. Feed them freshly hatched Artemia nauplii several times a week, and clean the container manually after feeding. Rotifers like Brachionus manjavacas can also be fed regularly. Clytia hemisphaerica is a well-established laboratory model organism, valued for its transparency, rapid life cycle, and ease of spawning, making it especially suitable for studies of development, neurobiology, and regeneration. The polyps can be maintained indefinitely but medusae have a shorter lifespan. Medusogenesis will occur if feeding sufficiently.
